Electronic photo display devices

Abstract

An electronic photo display device. The device comprises a panel, which is the size of a typical photo, an internal storage medium storing digital image files, and a central control unit. The central control unit acquires a digital image from the internal storage medium and displaying it on the panel according to a control command.

1 . An electronic photo display device, comprising: 
 a panel, which displaying digital images;    an internal storage medium, storing the digital images; and    a central control unit, coupled to the panel and internal storage medium, acquiring a digital image from the internal storage medium and displaying it on the panel according to a control command.    
   
   
       2 . The electronic %photo frame as claimed in  claim 1 , wherein the panel is the size of a typical photo.  
   
   
       3 . The electronic photo frame as claimed in  claim 1 , further comprising a transmission interface for connecting an external storage medium.  
   
   
       4 . The electronic photo frame as claimed in  claim 3 , wherein the central control unit further acquires a digital image from the external storage medium through the transmission interface and displays it on the panel according to a control command.  
   
   
       5 . The electronic photo frame as claimed in  claim 4 , wherein the central control unit further acquires another digital image from the internal or external storage medium to intermittently replace the currently displayed digital image on the panel.  
   
   
       6 . The electronic photo frame as claimed in  claim 3 , wherein the transmission interface complies with Universal Serial Bus (USB) protocol, Institute of Electrical and Electronic Engineers (IEEE) protocol, or Serial Advanced Technology Attachment (SATA) technology.  
   
   
       7 . The electronic photo frame as claimed in  claim 1 , further comprising a removable storage medium controller for connecting a removable storage medium.  
   
   
       8 . The electronic photo frame as claimed in  claim 7 , wherein the central control unit further acquires a digital image from the removable storage medium through the removable storage medium controller and displays it on the panel according to a control command.  
   
   
       9 . The electronic photo frame as claimed in  claim 8 , wherein the central control unit further acquires another digital image from the internal or removable storage medium to intermittently replace the currently displayed digital image on the panel.  
   
   
       10 . The electronic photo frame as claimed in  claim 7 , wherein the removable storage medium is a compact flash (CF) card, media card (MMC), memory stick (MS) card, smart media (SM) card, or xD-picture (XD) card.  
   
   
       11 . The electronic photo frame as claimed in  claim 1 , wherein the internal storage medium is a hard disk drive supporting a hot swap function.  
   
   
       12 . The electronic photo frame as claimed in  claim 1 , further comprising a power supply for supplying power to the panel, internal storage medium, and central control unit.
